Abstract (eng)
This work presents the phylum Chlorophyta, the green algae sensu stricto, and is
based on a combination of diverse sources and samples of various origins. A broad
range of knowledge and the structure of green algae should be presented within the
film. Initially, the movie indicates the general ecological importance of algae as
oxygen and primary producers and as catalysts of life. The success of the
Chlorophyta is illustrated by their various habitats as well as by eco-physiological and
anatomical aspects. For a better understanding, processes and structures are
explained in comparison to land plants. Life cycle and types of reproduction are
clarified within animations and time-lapses. The morphology of green algae is
versatile and provides a lot of different forms. Motile and immobile unicellulars,
filamentous, coenocytic, coenobial or parenchymatic (tissue like) organisms are only
a part of the various shapes. As green algae constitute the sister group to the land
plants, the thalli of green algae are highly suitable to compare corm and tissue.
Hereafter the phylogenetic structure and diversity of the phylum Chlorophyta is
discussed. The classes Ulvophyceae, Trebouxiophyceae and Chlorophyceae, are
presented and described by a selection of organisms. Biotechnology is a hot topic in
phycology. The last chapter elucidates this theme and shows isolation, cultivation
and economically relevant products of green algae.
The aim of this work is to summarize and mediate the scientific knowledge and
organisation of the phylum Chlorophyta within scientific documentary film. The main
focus was laid on a professional and contemporary mediation and production. The
film esteems clear explanations of various botanical terms and processes. The
scientific supplementary sheet resolves unanswered questions and information gaps.
